Dental Advisor rating
Stae is a highly recommended adhesive system designed for composite, compomer, and porcelain bonding. It received an 86% rating.
Complete and consistent hybridization
SEM observations of the Stae adhesive system revealed hybridization at the dentin-resin interface. The hybrid layer appears well developed with a uniform thickness of around 3 to 4 microns. Stae’s well infiltrated hybrid layer, compared to the other brands below, illustrates Stae’s complete sealing of the dentinal tubules, minimizing post operative sensitivity. Evident in the photographs is Stae’s “intimate adaptation of the interdiffused resin to the remaining sound tooth structure and uniform image density.
There are no gaps or voids visible within the hybrid layer. Such a characterization has previously been associated with adhesive systems with durable clinical success.
A similar hybrid layer was found with 3M Single Bond adhesive system.
With the Optibond Solo* adhesive, a less well defined hybrid layer resulted. Within the layer are areas void of resin interdiffusion. Further, the non-uniform image density suggests a lack of complete hybrid layer development.”
Non Bis-phenol A
Stae avoids the Bis-phenol A hormonal imbalance controversy, as it does not contain the related BisGMA resin.
High bond strength
Stae’s complete hybridization of the resin into the demineralized dentin results in high bond strength - 35 mpa.
Stae’s hybrid layer is continuous with the residual dentin layer with no evidence of separation or voids.
Stae’s “hybrid layer is very uniform with no variation in staining which represents a uniform interdiffusion of adhesive resin into the demineralized layer. The collagen framework appears totally encapsulated with resin.
Collagen fibrils within the hybrid layer show evidence of complete banding with no signs of denaturing or loss of structural integrity.
